A buffer overflow vulnerability was discovered in the the redis key-value database. The “redis-cli” tool could have allowed an attacker to achieve code execution and/or escalate to higher privileges via a specially-crafted command line.
For Debian 7 Wheezy, these problems have been fixed in version 2:2.4.14-1+deb7u3.
We recommend that you upgrade your redis packages.
